__pata_platform_probe - attach a platform interface : device : Resource representing I/O base : Resource representing CTL base : Resource representing IRQ and its flags : I/O port shift : PIO mask

Register a platform bus IDE interface. Such interfaces are PIO and we assume do not support IRQ sharing.

Platform devices are expected to contain at least 2 resources per port:

- I/O Base (IORESOURCE_IO or IORESOURCE_MEM)
- CTL Base (IORESOURCE_IO or IORESOURCE_MEM)

and optionally:

- IRQ      (IORESOURCE_IRQ)

If the base resources are both mem types, the ioremap() is handled here. For IORESOURCE_IO, it's assumed that there's no remapping necessary.

If no IRQ resource is present, PIO polling mode is used instead.
